NAudio.Midi 3.0.1

NAudio.Midi

Nuget

MIDI support for NAudio. Dual-targets net9.0 (cross-platform: the MIDI event model and file reader/writer) and net9.0-windows10.0.19041.0 (adds WinRT live MIDI I/O on Windows).

What's included

  • MidiFile for reading Standard MIDI Files (SMF)
  • MidiEventCollection and MidiEvent hierarchy (NoteEvent, NoteOnEvent, ControlChangeEvent, PatchChangeEvent, TempoEvent, TimeSignatureEvent, MetaEvent, SysexEvent, …)
  • MidiFileWriter helpers to produce MIDI files from a MidiEventCollection
  • Enumerations for General MIDI patches, drum notes, controller numbers, etc.
  • Windows only: WinRTMidiIn / WinRTMidiOut — live MIDI input and output backed by the WinRT Windows.Devices.Midi API (present only in the net9.0-windows build; the cross-platform net9.0 build omits them)

What's not here

Sending or receiving live MIDI through the legacy winmm-backed MidiIn / MidiOut uses the Windows Multimedia API and lives in the NAudio.WinMM package. (The WinRT-backed WinRTMidiIn / WinRTMidiOut above are the modern alternative and ship here.)

See the NAudio documentation site for tutorials and the full API reference, or the GitHub repository for full documentation and tutorials on working with MIDI files and events.

A patch release. The headline fix is packaging: the `NAudio` and `NAudio.Extras` meta-packages now ship a plain `net9.0-windows` leg, so WinForms and WPF projects targeting `netX.0-windows` get the full Windows stack again. * **Breaking:** `AudioFileReader` now throws `NotSupportedException` instead of `InvalidOperationException` when the cross-platform build is asked for a format it cannot read, and the messages simply state that rather than suggesting an `NAudio.Wasapi` install that could never have helped (#1407) * Fixed the `NAudio` and `NAudio.Extras` meta-packages resolving their portable `net9.0` asset on projects targeting a plain `netX.0-windows` TFM (the WinForms/WPF template default), which silently dropped the entire Windows stack — no `WaveOut`, WASAPI, Media Foundation, ASIO, DMO or WinForms types, and `AudioFileReader` throwing "MP3 file reading requires the NAudio.Wasapi package". Both packages now also ship a plain `net9.0-windows` leg (#1407) * Projects on a plain `netX.0-windows` TFM may now see `CA1416` warnings when calling WASAPI process-loopback capture. The warning is correct — those callers do need an `OperatingSystem.IsWindowsVersionAtLeast(10, 0, 19041)` guard — and was previously hidden because the only Windows asset available already implied that floor (#1407) * Sample and tool apps now roll forward onto newer .NET runtimes, so running them no longer requires the .NET 9 runtime to be installed (#1408) * Fixed `AiffFileReader` reporting too long a `Length` and throwing `IndexOutOfRangeException` when the SSND chunk declares a non-zero offset (#1405) * Fixed `AiffFileReader.Read` throwing `IndexOutOfRangeException` when the source stream returns fewer bytes than requested (#1405)
